Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to prevent accidental airbag deployment.

2. Retrieve and Address Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and document any SRS error codes.
Research the specific codes to determine the underlying issue.
If the code indicates a specific component (e.g., airbag module, seat sensor), proceed to address that component.

3. Inspect and Repair Components

Inspect the seat belt connections:
- Unplug the seat belt buckle connectors and visually check for dirt or corrosion.
- Clean the contacts and reconnect them.
Check the airbag fuses:
- Locate the fuse box and identify the SRS airbag fuses.
- Remove any blown fuses and replace them with the same amperage rating.
Examine wiring harnesses:
- Carefully inspect the wiring for any signs of wear or damage.
- Repair or replace any damaged wiring or connectors.

4. Clear Fault Codes

After addressing the issue, reconnect the battery terminal.
Use the OBD-II scanner to clear any stored fault codes.
Turn off the ignition and then restart the vehicle.

5. Final Check

Monitor the SRS light for a few minutes of driving to ensure it does not reappear.
If the light remains off, the issue has been resolved.
